Process chillers, and HVAC equipment in general, are prime real estate for all manner of insects. Technicians have all had the experience of getting up on the roof, and being forced to duck and dodge spider webs while they work. In the spirit of Halloween, here is a spider web we found at one of our sites in Pennsylvania. Although the spider wasn’t home at this web, there were plenty of other creepy critters on the roof that day… Have a safe and fun Halloween!
